Adjustment Method* Do not use this product without carefully reading the attached owner’s manual.

* To adjust, turn the adjustment knob with a slotted screw driver.

* Ensure that an external stopper (Stopper nut OP-020KB) is also used.

* Because the adjustment can be done in an analog manner, a* Do not turn the oil inlet screw located at the bottom of the main unit.
* Ensure that sufficient mounting strength is secured for this product. (As aguideline, it should be 2 to 3 times the maximum drag listed in the catalogue.)* Do not use this product in a vacuum or a location where it may come in contact with oil.
* Ensure that an eccentric load is not applied to the soft absorber(Allowable eccentric angle: within ±2.5°)50

Orifice typevalue between two integers on the indicator can be set.
* It does not have a lock screw for locking the adjusted setting.

3 Magnum Series● Screw the eccentric angle adaptor into
the main unit until the cap for the eccentricangle and the piston rod form a tightconnection. While maintaining this position,
fasten the main unit’s nut until secured.
● Use the eccentric angle adaptor whenthe eccentric angle is 2.5°or larger.
● The main unit can also be used as a stopper.
● Use it with a capless soft absorber.
● The maximum operating eccentric angle
with an eccentric angle adaptor is ±10°.
● The caps and the guides for inclined use
are not unbundled.
